DIY foundation waterproofing methods

We are building modular, the foundation is going in next week (9' high 10" wide poured concrete walls with 4" slab.

I'm thinking of doing the foundation waterproofing myself as long as you all don't convince me that it's a bad idea. With this in mind, what do you think are the best methods for the exterior and interior?

For the interior we're planning some sort of zero voc epoxy roll on coating that we can frame walls and put down some sort of flooring or keep the epoxy exposed.

Exterior wise we're a little confused with so many options and combinations.

Any help you can provide is appreciated!

suggest stego 15mm under the footer AND interior space wrapped UP & around the footer + 10" up the bsmt walls,,, trowel/brush on a good coating of hlm5000, hydrolastic, or equivalent to 5" above grade,,, local code may also require toe drain

The best way to waterproof your basement walls is a full-scale exterior waterproofing solution.

Do the outside right and you should not have to worried about the inside . No clue on DIY but anytime I have seen it done professionally it looks like a job I would not want to tackle . I would seek out local pro advice who might be able to provide a solution based on soil and drainage local to your lot.
